[PATCH v2 2/4] drm/amdgpu: Allow explicit sync for VM ops.

[Tatsuyuki Ishi]

From: Bas Nieuwenhuizen <b...@basnieuwenhuizen.nl>

This should be okay because moves themselves use KERNEL usage and
hence still sync with BOOKKEEP usage. Then any later submits still
wait on any pending VM operations.

(i.e. we only made VM ops not wait on BOOKKEEP submits, not the other
 way around)
